Effects of Technology on Education

!±8± Effects of Technology on Education

Education has changed significantly in the last twenty years. One of the main reasons education has undergone so many changes is because of technological development. In 1990, computers and other forms of technology served a minimal role in the classroom. Today, many if not most college students attend class with a laptop. I am writing about some of the biggest advantages technology gave to education.

Technology has made research much easier. Before online Encyclopedias, Google Scholar, JSTOR, and other online research tools were available, students were forced to spend numerous hours in the library. With the new tools, students can conduct research faster in the comfort of their homes. With Google and other search engines, students can find relevant information faster and more efficiently. Also, there is no more need for intensive memorization as information is more readily available.

New also technology allows for a faster, more efficient, and more interactive classroom experience. With Powerpoint presentations and projectors, there is no need for blackboards and whiteboards. With clickers, students can take quizzes during the classroom.

These developments also help improve tutoring services. Online tutoring programs are becoming available. One-on-one in-home tutoring programs are also being aided these developments. Tutors can bring laptops to sessions allowing them to look up information, and show examples to the student more easily.

Wi-fi technology allows students to study in more comfort and a more ergonomic setting.

New mathematical software such as Maple and Mathematica allows students to make a computer algebra computations more easily. Software like Matlab and Scilab allows students to make numerical computations more easily. There is no more need for a line rule. Advanced Texas Instrument and Casio calculators allow students to solve equations and produce graphs. Online software such as Webassign allows students to submit mathematics assignments online with instant feedback.

The internet allows students to read books and educational supplements at home. There is no need to go to a bookstore or library. Since many of these sources are open source or funded by advertising, students can access these materials for free. Wikipedia, Wikibooks are good examples. Students can learn more without leaving their house.

College applications and job applications can now be complete online. Students can deliver important paperwork to universities and employers at a much faster rate.

Online education allows more students to get an education. Handicapped students, students that have to travel a lot, and students with jobs can now complete their degrees wherever they go with a flexible schedule and often at their own pace. Due to its lower costs, online education also benefits lower-income students.

Technological development allowed the creation of new IT jobs and improved economic development in general.

Not all effects of technology on education are positive. Technology also allows students to cheat more easily. However, new technology allows instructors to detect plagiarism. Technological developments can also discourage critical thinking since answers are more readily available. Technology also encourages students to spend their time doing other activities such as playing video games and participating in social networking.

Overall, technological development in the 1990s and 2000s appears to be beneficial to education. Currently, technology improvement follows Moore's law which states that computers become twice as efficient approximately every two years. Today, one can purchase a well performing personal computer (without a monitor, software, and other accessories) for as low as 3.99. Recently, I have not spent over 0 on a desktop computer and it allowed me to do very advanced computations like high-sample Monte Carlo algorithms. If the trend continues, students all over the world will be able to afford desktops and laptops contributing to a better global education.

Ergonomic Office Equipment

!±8± Ergonomic Office Equipment

With the fear of lawsuits related to workplace injuries today, employers would be wise to consider investing in ergonomic office equipment. However, there are many other benefits, both to the employer and the employee, of using ergonomic office equipment. Until recently, it was not considered dangerous to one's health to work in an office setting. Offices seem relatively harmless compared to warehouses and factories where injuries are easily foreseeable. However, there are possible injuries that can happen in offices as well. Office related injuries are usually long term wear and tear problems. These types of issues can cause employees to use more of their health insurance and employer provided assistance programs as well as to miss more work and be less productive when they are working.

Some common injuries and health problems that happen to office employees are overuse injuries such as carpal tunnel syndrome and tendonitis as well as eye problems. Those who type on computers at their offices, are at risk of developing problems in their wrists, shoulders, backs and other parts of their bodies from sitting in chairs and using keyboards all day long. There are ways to lessen this impact, such as encouraging stretching, but, it is often worth it to invest in ergonomic equipment as a long term solution.

Some examples of ergonomic office equipment include special desks, chairs, keyboards and computer mice. Ergonomic desks often include slide out drawers for computer keyboards, and these drawers are typically adjustable so they can fit the appropriate height and can tilt and incline as needed. These can be a huge help in lessening carpal tunnel syndrome. In addition, special computer mice are available that are easier on the hands and wrists of those using them. It is also important to look up information on how to appropriately adjust the arm of the desk chair to appropriately match the keyboard and the mouse position in order to minimize the likelihood of carpal tunnel syndrome developing. As for problems in the shoulder and back and tendonitis in other parts of the body, ergonomic desk chairs can do a lot to help.

Ergonomic office equipment is typically a little more expensive than traditional equipment. It is usually worth investing in these purchases rather than saving money initially on uncomfortable equipment only to have unhappy, unhealthy and unproductive employees. If bought in bulk, employers can often find discounts on ergonomic office equipment. Sometimes, programs are available to help or to reward employers who invest in ergonomic equipment for the good of their employees.

If you are self employed or are responsible for your own office equipment, it is worth it for you to invest in ergonomic equipment that will be good for your health long term. Aside from the cost of replacing equipment later on down the road, this will be a one-time expense that will definitely pay off. You can also write off this equipment on your taxes, and you may be able to get discounts on your health insurance if you can prove that you are using equipment that will likely reduce visits to the doctor and health problems later on down the road.

Ergonomic office equipment is usually available at the same place where normal office equipment is found. As the market has changed to favor ergonomic equipment, and customers have become familiar with the risks associated with using office equipment, almost all equipment now is made to cater to be ergonomic on some level. However, some retailers and companies specialize in only ergonomic equipment and will offer more selections.
